4 To all whom 'it may concern:

Be it known that I, HENRY J. No'iz, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements. inTransmission-Gearing, of which the following-is a specification. Myinvention. relates to improvements in combined variable ,speed andreverse transmission gearing.

Aneimportant object'ofvthe invention is to providetransmission gearingof the above mentioned character, having means whereby the same mayverse directions at a plurality vof speeds.

A' further object of`the Ainvention -is tovprovide means for shiftingthe gearing from one speed to`an`other while the same `is operating ineither direction, without reversing the gearing.

A- further ob 'ect' of the invention is to` provide means for shiftingthe' reversing mechanism to cause the gearing to drive in oppositedirections while the variable. speed driving means is'a't neutral.v

A further obge t ofA :the invention is tol provide novel and simplemeans for moving the shifting rods or shafts. y

A further object -of' the invention is to provide transmission gearingof the above mentioned character, which is simple in construction,ineXpensiveto4 manufacture, convenient in, use, will occupycomparatively little space, and is not. liable to derangements.

Other objects and advantages of the invention will lbe apparent duringthe course of the following description.

In the accompanying drawings forming a part of this ,specification andin which like.

numerals are employed to designate like parts throughout the same,central horizontal longitudinal. sectional View through transmission fgearing embodying the invention, Fig. 2 is a transverse secline 2-`-2 ofFig. 1, Fig. taken on line- 3 3 of Fig. l1, Fig. 4 is a side elevation of a shifting fork orlever,Fig. 5 is an venlarged detail sectionthrough-the upper end of the fork, and, Fig. 6 isa side elevation of ahand wheel or knob.

.Journaled through suitable Vbearings 14' carried by the casing 10, is atubular driving shaft 15, having a driving-pulley or membe1 16, rigidlyconnected therewith. This driving pulley. is rotated in one direction byla single belt, receivingits power from anl engine or the like. It'is tobe understood.

that the driving shaftl may be continuously driven in the one directionby any other suitable means.

Arranged within the gear casing 1.0 are low, intermediate, and highspeed driving .pinions or gears 17, '18, and 19, which are -rotatablyorloosely mounted upon the driving shaftl, and are preferably providedhwith packing or bushing rings 20, as shown.

As more clearly shown in Fig. 3, each of the gears 17 to 19. embodiesan'finnerl hub member'- 21, rigidly secured thereto. This hub member -isprovided with an interior annular groove 22, vinto which projects'clutch elements or lugs v23, rigidly secured to the hub. member 21, andpreferably having av dove-tail connection therewith. The linner -or'free ends of these clutch elements or lugs 23 are preferably beveled, asshown. Arranged in coperative relation with the '.clutchelements or.lugs23, are preferably nreciprocatory clutch-elements-or bolts 24, disposedwithinv radially extending openings .25, formed through the drivingshaft 15.

The outer ends of these bolts'24 are beveled, as shown, whereby whenthe'same are released, by means to be describedfthe beveled ends of thelugs 23 will automatically shift the bolts 24 to the inner orvinactiveposition,- these bolts being detachably held in Vsuch The numeral 30designates a longitudinally movable clutch actuating. shaft, preferablyextending through the tubular drivin shaft 1.5. The longitudinalmovement of the shaft 30, in either direction, is positively limitedbystop-elements or rings 31 29, as shown.` Itjis obvious.i

means of balls 26, adapted gage the clutch-bolts, `whereby all of the`pinions are free to revolve upon the shaft 15. In Fig. 1, the shaft 3()is shown moved .from the neutral position, to'bring the exthe bolts 24,forcin the same outwardly l whereby thel interme iate pinion 18 islocked -to'the shaft 15. It is obvious lthat by mov ing shaft to theleft, the expanding member will engage bolts24 of the pinion 17, wherebypinion 17 is locked to the shaft 15 while pinion v18 is 4unlockedtherefrom. When the shaft 30 is moved to the right, expanding member 37will engage bolts 24 of the pinion 19, whereby pinion 19 is locked tothe shaft 15 while pinions 18 and 17 lare free to rotate thereon.

As more clearly shown in Fig. 1, the shift- 30 ing'sha'ft 30 is providedwith a plurality of vopenings or notches 38 to receive elements .orballs 39, movably mounted within openings formed through the drivingshaft 15, and urged inwardly by springs 41. The

35 means to longitudinally move the shaft- 30 will be describedhereinafter. The gear casing 10 is provided with bearings 42,v rotatablyreceiving a tubular driving shaft 43,'which is incapable of partaking 40of perceptible longitudinal movement. Ar-

rangedV within the' casing 10 and rigidly mounted upon the shaft 43 arelow, medium, and high speedpinions or gears 44, 45 and 46,'engagingrespectively with gears 17, 18 and 19, as shown. l The numeral 47designates a power distributing member or pulley, which includes thereversing mechanism. The member 47 is in the form of a pulley casing,and com.

50 prises casing-sections 48 and 49, arranged in end t0 end relation andrigidlyconnected by e means of bolts 50 or the like. The casingsection48'has a hub 51rotatably mounted upon a stationary tubular shaft 52,held in a stationary support or sleeve 53, as shown. The casing-section49 has a tubularhub 54 whichis' rotatably mounted upon thetubulan-driving 'shaft 43, the same'projecting' @into the pulley-'casingor member 47 and terminating at a point 55, the stationary shaftI52terminating adJacent the point 55,

xibut having no direct connection with'the n43.:- Arranged-within thecasing-sec- .s tion 48 is a planetary gear-carrier 56, -hav- "os. ing, atutu1ar, heb 57, rotatably mounted panding member 36 into engagementwith upon the stationary shaft 52.r Clutch means 58, identicalwith thatvdescribed in connecr tion with each of the pinions 17, 18 and 19, iscarried by the hub 5 and stationary shaft 5,2, to lock the hub 57 to theshaft 52, lwhen 70 desired. Rotatably connected with the planetarygear-carrier 56 by means of stub shafts 59, are planetary gears 60 '(seeFig. 2), engaging an outer annular gear 61,

formed upon the interior of the casing-section 49, and an inner controlor sun gear 62, rotatably-mounted upon the shaft 43. This sun` gear maybe locked to the shaft 43-to rotate therewith by clutch means 63,carried by the control 'gear 62 and the shaft 43, 80

and identical with the clutch means shown and described in connectionwith each of the pinions 17, 18 and 19. The hub 54'of the casing-section49 and the shaft 43 are provided-withclutch moan-S64, identical with sthe clutch means shown in connection with each of the pinions 17, 18 and19, whereby the casing-section 49 may be locked to the shaft 43fermtation therewith.

Longitudinally movably mounted within the shaft 43 is a shifting rod 65,carrying stop rings or elements 66 and 67, adapted to engage with theleft end of the stationary shaft 52 and a bearing 68, as shown. The

shaft 65 has a reduced portion 69, disposed 95' inwardly of the clutchmeansI 58, 63 and 64, A

and this reduced portion is provided with expanding members 70 and 71,adapted s when the shaft is shifted to the left to engage with theclutch means 58 and 63 to 100` simultaneously lock the planetarygear-carriers 56 to the stationary shaft 52 and the control gear'62 tothe shaft 43, while the clutch means 64 is inactive. When the shaft 65is moved .to the right, the expanding 105 members 70 and 71 engageclutch means 63 and 64 respectively, rendering the same inactive wherebythehub 54 is locked to shaft 43 and control gear 62 is also locked toshaft 43. When clutch means 63 and 64 are active, '110 the drivingmember or casing 47 rotates forwardly, but when clutch means 58 and 63are active, the driving member'47 rotates in a reverse direction.

The means for shifting the rods 30 and 115 comprises vtrunnion carryingmembers .or sleeves 72 and 73, which are longitudinally movably mountedupon the shafts 30 and 65, respectively, as shown. These trunnioncarrying sleeves are identical, each being prosage or recess 76, withinwhich is mounted 125 a vertically movable clutch or lock element 77,having a forked end 78, to enter an annular groove 79, formed upon theshaft 30 or'65, as shown. The clutch element 77. is

" be described.

As more. clearly shown in Fig. 4, the nuvmeral 84 designates arelatively stationary supporting arm or bracket, tothe lower end ofwhich is pivoted, as shown at 85, a vertically lswinging shifting lever86. This shifting lever 86 is forked forlproviding a air of .upwardlyextending arms 87 and 88. ach of these arms has its upper end forked,providing spaced arms 89, the upper -ends of which are provided withvertical slots'90 to receive the trunnions 74. It is obvious that whenthe lever 86 is swung in either direction, both sleeves 72 and73 will beshifted longitudinally. The lever 86 has an extension lever 91, rigidlyattached thereto -by meansr of bolts 92, or the like, as shown'. 1 4

Pivotally connected with the lever 86, as shown at 93, is a verticallyswinging guide lever 9,4, having the wlres 83 attachedl thereto, asshown at 95'. Near its lower end, the extension lever 91 (see'Fig. 6) is'provided with a transverse opening 96, receiving a' vertically swingingtransverse lever 97, to the ends of which are connected the wires 83.-This lever 97 is yrigidly connected with a rock-shaft 98, journaledthrough an openin in the extension lever 91, as shown. A han wheel orknob 99 is attached to the forward end of the bolt 98, while a clampingnut 100 has screw-threaded.engagement. with the opposite end thereof,which may be adjusted to Aregulate the turning movement of therock-shafts 99, whereby the same may remain in the desired position whenmoved thereto. It is'obvious that any other suitable means may beemployed to hold or positively lock the rock-shaft 98 in the positiveposition- By turning the hand wheel 99 in the desired direction 'eitherof the elements 4 77 may be moved to the elevated position, to lock the'corresponding trunnion carrylng sleeve to-its shifting shaft, while theother lock element is simultaneously moved downwardl whereby the othertrunnion carrying s eeve is freer-to move longitudinally uponitsvshifting shaft. v

The operation of the'apparatus is as fol- ;lows: The pulley 16 iscontinuously rotated in one direction, by any suitablemeans,

' whilethe power is. distributed from or by vthe elementor pulley-casing47, as by the same driving a belt, while other means may be employed.When the several parts of the apparatus assume the position shown inFig. 1, the member ,47, will be driven at re-l verse intermediate speed.1 The intermediate speed pinion I8 isnow locked to shaft 15- a reversedirection.

for rotation therewith, the expanding member 36 engaging withthe clutchmeans of the pinion 18. The'rotation ofthe shaft l'is accordinglytransmitted to the pinion l through the pinion `18. This drives theshaft'43 at' intermediate speed. The clutch means 64 being inactive,rotation of the joel shaft 43 cannot be imparted to the casin section 49through the clutch means 64 an hub 54. The clutch means 58 being active,

the planetary gear-carrier' 56 is held against rotation, whereby theplanetary gears 60 arev rotated upon their axes, by the control gear I62, which is locked to the shaft 43 f or ro-` j tation therewith. Theplanetary'gears engaging the annular vgear or pinion 61' rotates theelement or pulley-casing 47' in The element 47 may be driven at thethree speeds whileoperat--- ing in reverse, by shifting the rod 30. to

render the clutch means of either otth'- gears 17, 18and 19 active, ashereinabove' When it is desiredto shift-thefi. rod 30 in eitherdirection, for the purpose stated, the hand rwheel 99 (see Fig. 4) is'described.

When it is desired 'to changethe directionof rotation of'thefe'le# ment or pulley-casing 47, which in thepfresentinstant would be from" reverse to for; ward, the shifting lever 68 isfirst swung to the neutral position, bringing the rod '30 to the neutralposition, whereby all of the pin'- ions-17, 18 and 19, are rendered-idle upon the driving shaft 15. The hand wheel 99 is turned t the rightto bring the lever 94 to the neutral position, whereby both of thesleeves 72 and 73 slide upon shafts 30 and respectively. The shiftinglever 86 is now swung to the left, whereby `lock element 77 of sleeve 73is arranged in proxim-A ity to groove 79 of shaft 65, and upon furtherturning movement of the hand Wheel 99 `to the right,;lock element 77enters the same, whereby sleeve 73 is locked to the I' shaft 65, andsleeve`72 is free to slide upon rod 30. The shifting lever 86 is nowswung to the right effecting a corresponding movement of the rod 65,whereby expanding members and 71 engage the clutch means 63 and. 64respectively. These clutch means lock the casing section 49 and controlgear4 62 with the shaft 43 for rotation therewith, while the planetarygear-carrier is released, whereby the element 47 is rotated for- It isobviousl that the shifting lever 86 may nov7 befdisconnected from therod 65 and again employed to shift the rod VIt is to e understood thatthe form my invention herewith shown'and described 5 is to be takenvasia preferred example of the same, and that various changes, 1n theshape, size, and arrangement of parts may be resortedto withoutdeparting from the 'spirit of the invention or the scope of the subjoinedclaims.
